Bitcoin isnt a currency and unless it becomes one it could be worthless. Bitcoin is in decline. Not its price, which has almost reached 20k US dollars per unit last year, but its actual use as a currency. And this makes its rapid appreciation all the more puzzling. In my opinion, government agency should start implementing laws to accept bitcoin as currency before its too late.
Why do you think that the government needs to save bitcoin? Lol. They will observe from the side without losing anything at the same time. They never acknowledge it as a currency to prevent trade with bitcoins. Such operations are difficult to control. Governments do not make efforts to destroy bitcoin only because we spend bitcoins only after the exchange for Fiat.
